Cloud-Connected ZigBee Thermostat Demo

Demo Owner: Derek Snell

 

This demo combines several solutions from NXP and our partners. The demo is a thermostat application, using the Kinetis family as a communication gateway between a ZigBee network and connecting to the cloud. The demo runs on the MQX Real-Time Operating System (RTOS). It also uses the NXP PEG graphics library for the user interface displayed on an LCD. The ZigBee communication uses NXP’s BeeStack ZigBee stack, and connects with an NXP wireless development board programmed as a remote temperature sensor. The demo will also connect with an off-the-shelf ZigBee light bulb, and wirelessly controls it. The demo network connection is setup for Wi-Fi, using a Wi-Fi module from Qualcomm. The cloud connection allows the thermostat to be monitored and controlled remotely with mobile devices, and uses a solution provided by deviceCloud.io.

deviceCloud.io has told me that the URL for the DCIO agent has changed from app.deviceCloud.io to https://freescale-hvac-demo.devicecloud.io/deviceList.  That change has not yet been made in this demo or documentation.

Hello Derek,

Could you please specify the revision of the TWR-KW24D512 and the TWR-K70F120M? A customer has a problem with the I2C communication between these two boards and we'd like to discard a hardware problem due to different board revisions.

Freescale Cloud - Connected ZigBee Thermostat Demo doesnt work!

Best regards,

Earl.
